On my HTC Merge, why do I get a gray battery icon with an exclamation point?

[AC Question]

Htc merge and grey battery icon with exclamation point.

So last night I was using a Duracell car charger to charge my HTC merge and as the night goes on I notice that my phone starts to freeze whenever I plug it into a charger and that they is the grey battery icon with an exclamation point. I don't know why it is there or what I did to cause it. Could I have over heated the battery or overcharged it?

At what voltage and amperage did you charge it?
